Abstract: PURPOSE:To use a flexible light guide, to facilitate the designing and manufacturing of an optical system, and to perform an ultraviolet analysis remotely by coupling hollow pipes in plural stage at joints, and providing an optical fiber for alignment in each joint part. CONSTITUTION:The ultraviolet light guide uses a flexible tube D. The optical fiber C is fixed in the tube D while its input and output terminals E and F are aligned to an optical axis by proper holders G. The hollow pipes A and B forming a transmission line are provided with a condenser lens H for allowing light to enter the terminal E efficiently and a collimator lens J for collimating and transmitting light from the terminal F. The lenses H and J use the same material. The transmission line is made airtight by making the A, D, and B airtight on the whole or making the A and B airtight individually and making the contacting part between the E and F and holders G airtight. Plural stages of constitution shown in a figure are coupled together to obtain the ultraviolet light guide which is flexible and has excellent transmission efficiency.

Title: Heel bottom material and heel part
Inventor: ODA NORIO
IPC: A43B13/18
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent completely the heel portion of shoes, etc., from splashing muddy water on a road surface during walking. SOLUTION: A heel bottom member 3 is attached to the bottom of the heel 2 of a shoe with an adhesive 4. The heel bottom member 3 is formed of a flexible open-cell foam 5 such as polyurethane, etc., the sides of which are covered with an airtight coating 6, and the open-cell foam 5 is exposed at the bottom. When one walks on a road surface with these shoes on, the heel bottom member 3 made up of the open-cell foam 5 having flexibility is compressed when it touches the ground, and the open cells of the open-cell foam 5 return to the original shape when it leaves from the road surface, producing negative pressure in the inside of the material, and absorb muddy water rapidly into the inside of the heel bottom member 3.  In addition, the airtight film 6 prevents the heel bottom member 3 from sucking air from the sides, and thereby eliminates reliably the suction of muddy water sticking to the heel bottom member 3.

Title: Pulverized coal distributor
Inventor: KOGA MINORU
IPC: B65G53/66
Filed: 1983-05-04
Abstract: PURPOSE:To enable pulverized coal from a coal mill to be distributed in uniform density to each branch pipe, by rotatably installing an inclinable slanting plate to the branch part of a main piping. CONSTITUTION:The flow rate of pulverized coal in each branch pipe 3 is measured by a flow meter 26 installed in the branch pipe 3, and when a difference in the flow rate of pulverized coal between the branches 3 is produced, the protruding distance of a piston rod 25 of a slanted cylinder 24 is varied through an on-line by means of a microcomputer. In the case of, for example, the branch pipe 3 having the low flow rate of pulverized coal, the protruding distance of the piston rod 25 of the slanted cylinder 24 is changed. For example, in the case of the branch pipe 3 having low flow rate of pulverized coal, if the piston rod 25 of the slanted cylinder 24 is protruded, a locker arm 21 is turned around a pin 22 serving as a flucrum, a reciprocating shaft 15 is pressed against the main piping 1 side against the repelling force of an elastic body 19 by means of a projection 23, and a slanting plate 5 is inclined at a given angle through the medium of a link mechanism 17. This enables pulverized coal from a coal mill to be distributed in a uniform density to each branch pipe.

Filed: 1982-05-11
Abstract: PURPOSE:To perform address conversion at a high speed, by detecting the coincidence at a comparing part between the key part of a read-out data fed from an address converting buffer and a part corresponding to the address information which is set to an address register, and obtaining a real address. CONSTITUTION:A part of the real addresses on a virtual machine identifier and a virtual machine is used as a key part among the data read out of an address converting buffer 2 at a real central processor. A part of a data other than those which are turned into the address information is outputted to a signal line 104. A comparing part 3 compares the data on the key part which is delivered from an address register 1 via a signal line 100 with the key part which is read out of the buffer 2 via the line 104. When the coincidence is obtained from this comparison, the state of the signal of a signal line 108 goes to 1. A selecting part 4 selects the data part on the contents of the buffer 2 which is fed to a signal line 105, and this data part functions as a part of a real address on a signal line 107. This system enables the address conversion at a virtual machine system to obtain a high-speed.

Title: Level decision circuit
Inventor: AKAGI YOUZOU
IPC: G01R19/165
Filed: 1983-05-06
Abstract: PURPOSE:To simplify a level decision circuit so that it includes only one constant voltage circuit by making a level decision voltage independent of the variation in one of supply voltages of two supply power sources. CONSTITUTION:When the input voltage applied to the inverted input terminal of an operational amplifier 16 is lower than a decision voltage VL, the decision output of the amplifier 16 is a positive voltage, and when the voltage exceeds a decision voltage VH determined by constants of resistances 15, 12, and 13, and the output voltage of a constant voltage circuit 18 connected to a plus source voltage, the decision output is inverted into a negative voltage. Consequently, a diode 14 connected to the resistance 13 is biased reversely to cut off a feedback circuit, and the voltage VL is determined by the constants of the resistances 12 and 13 and the output voltage of the circuit 18; when the input voltage drops below the voltage VL, the decision output of the amplifier 16 is inverted into the positive voltage again. Therefore, there is no need to provide a constant voltage circuit on the minus source voltage side where there is no influence of the variation in supply voltage, and the constitution of the level decision circuit is simplified.
